We're dividing 74622960 by 91 
The aim is to understand the frequency of 91 in 74622960.

On to step 1:
91 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 91

Moving on to step 2:
91 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 91

On to step 3:
When dividing 746 by 91, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 18 after subtracting 728 from 746.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 91

Moving on to step 4:
If we divide 182 by 91, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 182 from 182 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 91

Going ahead to step 5:
91 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 820.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 91

Advancing to step 6:
91 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 8200.0
The remainder is 29 after subtracting 0 from 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 91

Let's proceed to step 7:
When dividing 296 by 91, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 82003.0
Subtract 273 from 296 to get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 91

On to step 8:
91 goes into 230 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 820032.0
If we subtract 182 from 230, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 91, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 820032.5
If we take 455 away from 480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
91 goes into 250 2 times with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 820032.52
Subtracting 182 from 250 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
The number 91 fits into 680 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 820032.527
If we take 637 away from 680, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
If we divide 430 by 91, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 820032.5274
Deduct 364 from 430 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
91 goes into 660 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 820032.52747
If we subtract 637 from 660, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
91 goes into 230 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 820032.527472
Subtract 182 from 230 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
The number 91 fits into 480 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 820032.5274725
Subtracting 455 from 480 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 16:
250 divided by 91 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 820032.52747252
Subtracting 182 from 250 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 820032.52747252 with a remainder of 6.8e-08.
